speed up chemical reactions by lowering the activation energy needed for the reaction to occur. This allows the reaction to happen more easily and quickly. Enzymes are specific to their substrates and promote specific reactions.

Substrate molecules bind to enzymes where?

The bind in the active site.


Why must a molecule have a specific shape if it is to be a substrate of an enzyme?

Active sites of enzymes (where the substrates fit in) are substrate specific, and are complementary to the shape of the molecule (substrate). In this way, enzymes can only act on a specific substrate, since that is the only shape that it will accommodate in the active site.


Why do enzymes generally bind to only type of substrate?

Enzymes act only on a specific substrate due to the active site of the enzymes fits perfectly with the substrate. Like 2 puzzle pieces, they can only go together and not with anything else.


Why will only certain substrate molecules fit into the active site?

It will only bind with the enzymes active site of the shapes are complimentary and enzymes are very specific


What feature of enzymes controls which substrate they act on?

The feature of enzymes that controls they substrate they act on is called the active site of the enzyme. The enzyme is a protein. Each active site is specific too the substrate which it acts on. The substrate may fit into the active site via a lock and key mechanism or by an induced fit. The active site attracts and binds with the substrate in order to allow a reaction to occur faster. The substrates are also called the reactants. =)

How does an enzymes active site relate to its substrate-?

An enzyme's active site is a specific region where the substrate molecule binds and undergoes a chemical reaction to form the product. The active site's shape and chemical properties are complementary to the substrate, allowing for precise binding and catalysis. This interaction between the active site and substrate is crucial for enzymes to function effectively.


Why am enzyme can be used to catalyst a large quantity of substrate?

Many times enzymes have multiple active sites that allow for many simultaneous reactions. For example, it's possible to have a fourth of the number of enzymes as substrate molecules, but the enzyme may have four active sites, resulting in one active site per substrate molecule.


Does the active site of an enzyme have a shape that is specfic for its given substrate?

Yes, the active site of an enzyme has a specific shape that is complementary to the shape of the substrate it binds to. This allows for precise recognition and binding between the enzyme and its substrate, facilitating the catalytic reaction.
